What you thought your terminal values were changed. Your terminal values didn’t necessarily change.
Deep ecology, in itself, entails that you value (some metric of biology) as a terminal value. Since I no longer believe in it, my terminal value for it did change.
It’s sort of like this: if a religious person had his religion (God) as a terminal value, but his God was then definitively proved not to exist, then he would have to change his terminal values too
Is there anything about terminal values that means they are immutable? What’s wrong with valuing something for its own sake, and then later changing your mind?
well, in the long run, we’re talking about maximizing our utility, which means taking the time-integrated utility function.
so yes true, valuing something for its own sake actually could count even if it’s not permanent.
